This project uses a web-based enviroment to allow for the virtual reconstruction of pre-modern manuscript books that at some time in their history were taken apart, "broken" into pieces and dispersed. Using IIIF technology, the Broken Books program allows me to contribute images and information, including cataloging metadata, about undiscovered leaves of the Llangattock Breviary, with the goal of virtually reconstructing the original manuscript.Please also see a second Broken Books project at: http://brokenbooks2.omeka.net.
